If you guys can get it here I'll take a look, nothing makes sense. Lose of power steering and lose of engine power tells me lose of acc belt If a fluid got on the belt it would slip, that'* if it don't come off.

Is there any chance it was over heating
Ensure that the engine coolant temperature is not above 128°C (262°F). This condition will cause the PCM to operate in Coolant Hot Mode. While in Coolant Hot Mode, the PCM will turn fuel OFF to three cylinders to keep engine temperatures from reaching damaging levels. Coolant Hot Mode will be perceived as a lack of power, miss, or rough idle. If the vehicle is operating in Coolant Hot Mode, refer to Engine Overheating .
maybe this condition caused loss in steering fluid pressure.
This is the only way I can think the 2 conditions can happen together.
the shop said leaking gasket (again over heating?)

Hopefully not the case.

Ok so i went down there yesterday, the guy at the shop said he coudln't find anything wrong with the car. I drove it back to school for my brother. Right after getting on the road I noticed the temp gage well over 200 fans would kick in just before the last slash before the red. I thought that was a bit high. The engine temp gage was moving a lot which I found odd. Everything runs fine, so not even sure what it could be maybe the coolant temp sensor?

Thought you were bring that over here? It really sounds like air in the cooling system. A bad thermostat tends to open to soon or stay open causing the engine to never really heat up good. Over heating tends to be air in the system, some kind of restriction, or a problem with the water pump.
